I have been running SheepShaver for years under Mac OS X 10.9.5. Last week I updated to 10.11.6. I also had to update to SheepShaver_UB_20140201.The sole purpose for running SheepShaver is to run Gene 4.3.4. https://www.ics.uci.edu/~eppstein/gene/When launching Gene and click in the file opening window that appears, SheepShaver(!) crashes.

You may want to try the latest Sheepshaver build 2.5 from 21. June 2018..

Best try the July 11 2018 2.5 version build, it mostly solves a caps lock issue when SheepShaver is launched with caps lock on that existed in the previous 2.5 version builds. (A July 12 build also existed that tried to further solve the caps lock issue, but instead made it worse again).http://ronaldpr.home.xs4all.nl/sheepsha ... 1_test.zip

Probably more important: Make sure that in SheepShaver Preferences > Miscellaneous the option "Ignore Illegal Memory Accesses" is enabled.
